shakey, i understand about the 1667 ohms bit, but, shouldnt it be lower than that (exact figure not known at mo) to do away with an unreliable earth path??
depends what you mean by 'do away with'
No value would allow you to do away with an unreliable earth
Or are you refering to the value of 200 ohms for TT earth electrodes?
This is the max value at which it could be condidered a 'stable reading', but is not a max value as far as the RCD is concerned
there is no 'leeway' for an unreliable earth
